BAILEY S. WESOOTT, OF OORNING, NEW YORK, ASSIGNOR OF ONE-HALF HIS RIGHT TO LORAINE DODGE, OF SAME PLACE.

IMPROVEMENT IN WHIFFLETREES.

Specification forming part of Letters Patent No. 140,327, dated June 24, 1873; application filed April 26, 1873.

To all whom it may concern:

Beit known that I, BAILEY S. WEsooTT, of Corning, in the county ot' Steuben and State ot' New York, have invented a new and valuable Improvement in Whifdetrees; and I do hereby declare that the following isa full, clear, and exact description ot' the construction and operation ot` the same, reference being had to the annexed drawings making 'a part.

of this specilication and to the letters and 1i gures of reference marked thereon.

Figure 1 of the drawings is a vertical secY tion of my whiftletree. Fig. 2 is a top view ot' the same. Fig. 3 is a detail view.

This invention has relation towhiletrees, evene's, or sin gle-trees; and it consists in the construction and novel arrangement of the spring-staple, whereby, in the draft over rough roads, or in striking an obstruction, the shock upon the shoulders ofthe horses is materially lessened. The object ot' this invention is to provide for the comfort of draft animals in their labor, and thus increase their health and usefulness. 4

In the accompanying drawings, the letter A designates the wooden shaft of the whit-fletree, in which are bored two holes, b b. To prevent wear on account of the working of the arms of the staple, these holes are lined by means of the tubes c c. Plates d d are fastened to the front and back ot' the whiftletree, the latter being perforated for the passage of the arms of the staple. The object of these plates is to secure and steady the staple in its working. rlhe staple e consists of an inolosed loop or ring, g, having its rear edge h squared against the face of the plate d and of the arms k, having screw-threads for engagement with nuts my, of diameter sufficienti y small to be introduced within the tubes c. s indicates spiral springs, located on the arms 7c. In assembling theparts the plate cl/ is Iirst placed on the arms k, then the springs s are slipped on, and iinally the nuts m, which are screwed up until the staple does not rattle onv the plate, and the proper tension is obtained. Then, the plate d having been secured to the back ofthe whit'tltree, and lining-tubes c having been introduced into the holes b, the arms k with their nuts and springs are inserted within the tubes c, and the plate d is securely fastened to the face of the tree.

That I claim as new, and desire to secure by Letters Patent, is-

In a whifiletree, the combination ofthe staple e having the loop g and threaded arms k with the adjustable nuts fm, the springs s, and the removable stop-plate d', substantially as speciiied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

BAILEY S. WESGO'II.
